waheguru ji ka khalsa waheguru ji ki fateh. when Guru Gobind Singh ji revolutionised Sikhism at vasakhi 1699 with the Khande Batte de Pahul...HE ORDERED that from that moment ALL Males will carry the SURNAME SINGH and all Females will carry the surname KAUR. That message is repeated at all Amrit sanchaars even today... BUT then we go ahead and IMPROVE on GURU JI's orders and ADD "KHALSA" as a SURNAME. We even shorten the SINGH / KAUR t just initials S and K or eliminate them alltogether...BUT never drop or shorten the KHALSA....manmatt or gurumatt ??? Jarnail Singh. PS. btw, there are NO SURNAMES in my name.... the "arshi" is a pen name ( also referred to as nom de plume ) used by writers and poets ( i fondly imagine i am one) etc in their writings to identify themselves and the "gyani" is an academnic degree awarded after passing a public examination called gyani exam ( Hons in Punjabi) by Punjab university and others.
